GSoC (Google Summer of Code), a program where university students spend their 3 month summer break coding on an open source project.
That time finally comes. After almost one year I have been lurking, day
dreaming, it’s time to decide whether I will participate or not. It’s not easy
to find organization who fit with who I am. But anyway, this year, I will try.
Despite administrative prerequisite, such as proof of enrollment, there are some technical stuff involving coding activities we need to do, which is fun. This is a list of what I’ve done so far in order to be considered as good candidate:
Pick a project with programming language that I passionate about
There is a word “code” in Google Summer of Code, meaning programming will be my main
activity in this program. So, I must find which project that has programming
language, that I familiar with. This is to avoid, I will stuck about the tasks
that will assigned to me as a program applicant.
Actually, it can be done even long ago before the program being announced. I can look at the GSoC archive. But, sometimes term will change as the organization announced. Some organization will participate again, while others not. So, for me it better to prepare after the program announced officially.
From there, I can see which project fit with my programming language, one that I love. So, after some effort of filtering and analyzing, then I choose an appropriate project, I will not find a big technical barrier to pass this program.
Pick a project that fit with my knowledge
This means, I must look at the project task. With given time frame, which about
just 3 month, does it sound realistic that I will finish my task? That it’s, be
realistic is the key. Measure the difficulty of the task. When I face something
very unfamiliar and need more time to learn, I prefer to skip this. Because I
don’t want to spend my time in things that I less understand.
For example, this year, I choose project from GNU Wget that use C as their programming language base, which currently I am familiar with. And for the task, I pick idea of “Improvement of test suite using Libmicrohttpd”.
Get enganged with community
After I found the project that I want to apply, I must introduce myself to the
community. This is important step I must do. Because without it, mentor cannot
help me when I face difficulty.
Find the place where they collaborate. There are some choice like mailing list, slack, gitter, irc, etc. GNU Wget use mailing list as they medium to communicate between developer. I send welcome message there, and replied kindly by other members. Follow their rules. Basically, there are some rules to be obeyed: - Use plain English. GSoC is global program and use English as it language for communication. So, I need to use English in my conversation. - Not to send message directly to the mentor or other person in the community. This is considered to be rude. Instead, I will use mailing list if I need to send a message. - Avoid top post when I reply an email.
Learn their environment, workflow and code base
After I “Say Hi!” to the organization, now it’s time to dive into their code. Find the
repository. In Wget, their main repositories are hosted in Savannah, Github and
Gitlab. So, I clone the repo and then build the software from source.
I have successfully built Wget from source. Then I try to trace what the program do using gdb, to take a look what is going on inside its process.
I familiarize my self with git, because Wget use git as its version control system. Also the project uses Github to consolidate patches, open issue, write wiki, etc. I try to hanging around on there. It fancy design keep me comfort with environment and workflow of the project.
Submit a patch, event with a trivial one
This patching section required quite technical skill. For newcomer like me, I feel a bit
confuse about what patch I can submit. Then, with guide from my mentor, I was
given an idea what simple task can be submitted. I pick an easy one. A testing
unit. Because, he mention, that Wget unit testing is still far from perfect. I
will take it for my chance. I try to add a function to reach more coverage in
the project unit test.
In order to merged into upstream, I need to make pull request on that project. To be honest, it is my first time pull request in a real open source project. Of course my patch will not merged automatically to the upstream. Mentor and the community members will review first before it can be accepted. And after several step, edit code, re-push commit with guide from my mentor and other contributors that help me, finally my patch get merged on the upstream. It’s a nice feeling for a rookie developer can have.
Write a good proposal
After all, to be accepted in the GSoC program itself, I need to upload a proposal. The proposal must be good enough to be considered accepted as GSoC candidate. I pick the idea from list project that mentioned in project website. I create a draft from this and share to other members. I receive a lot of feedback. Thanks for who was concerned, so I can make improvements to my proposal. After I feel it ready, I upload my final proposal to GSoC official.
That was my short list for what I do in this GSoC. And because the time between the date of proposal submit and the announcement of accepted applicant is a month long, I will use it to get more familiar with project code base.
